The deduced amino acid sequence of OpMyb24 , which was obtained from a zygotic embryo cDNA library, showed extensive homology to the snapdragon proteins Myb308 and Myb330, and to maize protein Zm38. Furthermore, the OpMyb15 gene, from an oil palm suspension culture (OPSC) cDNA library, ...
转录因子通常由几个独立的功能叶植物玉米中克隆出与色素合成相关的ZmMYBCl 域组成,包括DNA结合功能域、转录调控区(激活基因以来,大量Myb类基因从各种植物中得以分离 et et 或抑制)、信号分子结合域和核定位信号区等。根据 鉴定(Oolaya1.,1996;Loguericoa1.,l999;Miyake et et DNA结合功能域的结构,转录因子...
在高浓度 ABA 条件下, MYB96 可通过调节组蛋白脱乙酰酶 HDA15(histone deacetylase)促进组蛋白 H3 和 H4 去乙酰化并抑制 GTP 结合蛋白 ROPs(Rho-related GTPases of plants) 的表达,从而在 ABA 途径中起负调控作用,包括 ABA 介导的气孔关闭和干旱响应[69].在 MYB96 受 MIEL1(RING-type E3 ligase)泛素...
this protein is characterized by four and a half MYB repeats. This protein is a subunit of the SNAP complex 4 that is involved in snRNA gene transcription.Arabidopsis thaliana,Beta vulgaris,Vitis vinifera, and many other plants have only a single copy of ...
第 3 个螺旋被认为是"识别螺旋", 其负责识别 DNA 结合位点,并以此结构结合在目标 DNA 的主沟中(图 1).根据与动物 c-myb 中 3 个重 复序列 R1,R2 或 R3 的相似性以及 R 重复序列的 数量, 将植物 MYB 家族分为 4 类 :1R-MYB/MYB- related,2R-MYB/R2R3-MYB,3R-MYB/R1R2R3-MYB 和 4R-MYB...
The expression of a majority of phenylpropanoid genes was positively and negatively correlated with ZmMYB31 and ZmMYB42 expression respectively in maize. In sorghum the expression of most phenylpropanoid genes also negatively cor- related with SbMYB42 expression but only a weak positive correlation ...
it is phylogenetically and functionally related to the R2R3-MYB repressors, however24. Since the elegant work with petunia MYB27 and MYBx illuminated the network of anthocyanin related transcription activators and repressors, increasing MYB repressors have been characterized in model and crop dicotyled...
MYB转录因子在植物抗逆胁迫中的作用及其分子机理_刘蕾
A phylogenetic tree was constructed using the neighbor-joining method with the protein sequences of PtoMYB156 and other MYB factors involved in the regulation of the phenylpropanoid pathways (Fig. 1C). Phylogenetic analysis showed that PtoMYB156 is more closely related to AmMYB30853, EjMYB254...
根据每个MYB蛋白中含有的R结构个数和重复种类的不同,MYB蛋白可分为4R-MYB、2R-MYB (R2R3-MYB)、3R-MYB (R1R2R3-MYB)和1R-MYB (MYB-related)这4类相关蛋白[15]。其中,最小类的4R-MYB蛋白中的每个基因包含4个R1/R2重复序列,且只在极少数植物基因组中进行编码[16],目前仅在模式植物拟南芥[17]、葡萄...
